Application January l31, 194i), serial No. ritratti) 01; 2045)- v I 3 Claims.

This invention relates to a building corner piece, and vmore particularly to a building corner piece of simulated masonry siding of the type comprising a rigid insulationboard base having a coating with combined waterproofing-.and decorative characteristics. Y v

.In the use of building covering material of Vthis character, it is customaryvthat the corners of a building be provided with a corner piece which overlies the .ends of the wall panels adjacent to the building corner' for `a sufficient extent to `pro-- vide a tight weatherY sealed joint at the building corner. Thus, if it is necessary tocut a panel adjacent the building corner and thereby expose the raw insulation board base thereof, which base is usually formed of material such Yas -Celotex or Insulite, and is subject to liquid labsorption and quickdeterioration when exposed tothe weather, .the corner piece will lprotect such rawfedges and consequently make the siding material weather tight throughout. However, it will readily be seen that there is one marked disadvantage in this practice; namely, the vfact that the corner piece is off-set from the wall panels whose outer ends it overlaps. I

Inasmuch as it is the primary object of the building covering material to simulate a natural masonry product, such as brickwork, which is not customarily laid up with olf-sets at building corners, the use of the corner pieces is a definite disadvantage to the building covering material from the appearance standpoint.

While I propose to continue the use of the offset and overlapping corner piece, it is the pri- `mary object of my invention to so form the same as to conceal or camouflage as much as possiblev from the vision of the average -casual observer the overlapping `position of the corner piece.

A further object of my invention is to provide a corner piece of the character above mentioned having its Vertical edges configured or shaped to taper toward the rear surface thereof whereby to conceal the thickness of the corner piece.

A further object is to provide a corner piece having a rigid base coated with 'waterproong and decorative material to which a masonry simulating design is applied, `and wherein the opposite longitudinal edges of the corner piece taper toward their rear surface to permit merging of said design with the design on the siding panels overlapped by said corner piece.

A further object is to provide a corner piece adapted to be positioned in overlapping relation to siding panels which is constructed to present theleast possibleprojection against which ob#- jects can strike to injure the same.

, Other 'objects Vwill'be apparent scription and appended claims.

Each of Ythese panels preferably .comprises a composition` hoard, base II rhaving applied to the outer 'face thereof a .coating .I Z ofasphalt, bituminous, or other waterproofing material which is suitably coated with coloring and surfacing material (not shown) such as brick particles, grit or granules. Y'

The face of each panel has a design applied thereto in any suitable manner to provide a plu-V rality of horizontal lines I3 simulating horizontal mortar joints of a different color and appearance than the remainder of the face of ythe panels,

and also Vertical panel lines I4 extending between I the lines I3 and in staggered relation to simulate.,

vertical mortar joints. It will be understood that the-lines I3 and I4 may be of any conventional character, and as here illustrated are depressed at I5 to give the appearance of raked mortar joints.

contrast with the surfacing material, or may be formed by grit or granular material of Ia color contrasting to that applied to the remainder of the panels which are outlined thereby to outline dinal edges of the corner I1 are tapered at`l8.V As' illustrated in Fig. .3 this taper may bea y straight taper extending from the reary edge of the board IIn at an'acute `angle and merging at I9 with theface of the board II on a gradualY Fig. 2 isa perspective View `of my inriprove'dY Lines I3 and I4 may have the bitumi- Y nous material or asphalt I2 exposed for color curve which tends to eliminate therefrom the appearance of ra corner. The Weather proof and decorative coating material is extended to cover the tapered edges I8 at 20. A plurality of horizontal mortar simulating lines 2|, shown in Fig. 3 as comprising depressions; and similar in all respect to the lines I3 and I4 in the siding panels I0, serve to impart to the outer face of the corner unit the appearance of a plurality of masonry units such as brick faces 22.

It will be observed that, by this corner construction, the tapered ends I8 together With the curved corner I9 tend to conceal and camouflage the three dimensional character of the coating at the longitudinal edges of the corner pieces, regardless of the angle from which the same is viewed. In this connection, it Will be obvious that when any corner structure is viewed `from an angle such as Fig. 2, this overlapping position of the corner piece with respect to the side walls of the building, is not particularly noticeable, even with the present day corner construction utilizing the straight perpendicular edges. However, when the conventional corner piece is viewed at an angle, as in Fig. 1, the thickness of a straight edge corner piece is readily apparent. In the instant construction, the curvature of the outer corner ofthe corner piece at I9, together with the tapered form thereof, produces a different optical effect than a straight edge panel, as best illustrated in Fig 1. The offset relation of the corner piece to the side wall is substantially concealed. l

Another important advantage of this improved corner is that the mortar joint simulations therel of match better with those of the overlapped siding panel and therebyA avoid an objectionable break-joint appearance. Still another advantage of the construction is that it does not provide a projection or shoulder o-f such character as to be readily damaged if struck a glancing or end blow. There are various other Ways by Which the same. advantages aforesaid can be achieved. Thus a modied form of the longitudinal edge of a corner piece is illustrated in Fig. 4, wherein said edge is formed on a gradual curve 25 merging with the outer face of the panel II and meeting the rear face of the panel II in acute angle relation. Some individuals may prefer the curved form as illustrated in Fig. 5 to the straight tapered form illustrated in Fig, 3, but the results in both instances are the same.

I claim I 1. A building Vcorner piece adapted to overlap end portions of building panels each simulating a plurality of masonry faces mounted on side Walls adjacent a building corner, comprising a pair of xedly angularly disposed narrow elongated rigid panel portions, the outer longitudinal edges of said panel portions being tapered and merging in a gradual curve with the outer faces of said panels, said tapered portions each defining an acute angle with the rear surfaces of said panel portions,y and a Waterproof and decorative coating covering the outer faces and tapered portions of said panel lportions andsimulating a plurality of masonry faces .andadapted to complement the pattern of masonry faces on said panels.

2. A buildingl corner piece` adapted to overlie end portions of building covering panels on adjacent building Walls and each having a plurality of horizontal `mortar joint simulations, comprising a vertically ,elongated rigid member of- L- shape in cross section, said member having its opposite longitudinal edges taperedfromiront to rear to conceal the thickness thereof-when in overlying relation to said panels, said member having a plurality of horizontal mortar joint simulations extending thereacross and across said tapered edges to merge with the joint simulations of saidpanels. y

3. A building corner piece as dened in claim 2, wherein said tapered edges are curved to merge With therres'pective front faces of said member and to form yacute angles with the respective rear faces of said member. Y
